A fish story

I am a sturgeon and exact. I have no preconceptions.
Whatever I see I swallow immediately
Smaller fish, fishhook, just as it is by taste or dislike.
I am slippery and wet- I am only being truthful;
Black-eyed, four seas cornered, I generally meditate.
My scales are slate grey, no wait, olive brown,
And did I tell you, they flicker in light and reflect it carefully;
I like to hide in shadows of waves when trawlers appear,
Searching my reaches for caviar- pickled roe on a silver plate;
I much rather be swimming in a lake with an alligator gar,
With bits of my caudal fin snug in its mouth- wait, what a terrible fish;
Its long snout with razor sharp teeth, I would rather be drowned!
